Suggested March 2024 Install Os X Mountain Lion Developer Preview On Old Unsupported Macs

If you read the OS X Mountain Lion system requirements and got discouraged that the next version of OS X won’t support your computer, don’t give up hope for that old Mac quite yet!

The method has reportedly been tested on MacBook 2007 MacBook2,1 and MacBook 2008 MacBook3,1 but presumably will work on other unsupported Macs as well. If you want to try this yourself, be prepared to get your hands dirty, and backup your Mac before beginning. You’ll need access to the Dev Preview, an officially supported Mac in addition to the unsupported Mac to copy some files over, the guide calls for switching hard drives but you could do the same with target disk mode. Regardless, you’ll need a fair amount of patience.

Here are the full instructions according to hackerwayne on MacRumors forums:

1. Get a copy of Mountain Lion, I got mine from Apple. If you’re not a dev, maybe you can get it at “the bay full of pirates”

2. Make sure you have a Mountain Lion compatible Mac, Im using a MacBook 2.4GHz Aluminum 2008

3. I have no FireWire to do target disk mode, so i removed the HDD from the MacBook White, pop it into the ML compatible Mac and install Mountain Lion like normal.

4. Get everything set up, until you reach the desktop

5. Now, remove the HDD from the compatible Mac, pop it into the MacBook White. Restart the MB White and hold down “CMD + V”. It should say “Incompatible Mac detected. Reason: Mac-F4208EC8” the “Mac-F4208EC8” is a unique ID for your Mac, so copy that down.

6. Remove the HDD from the MacBook White, and again, pop it into the compatible Mac, reboot back into Mountain Lion. U Now, navigate to ‘/System/Library/CoreServices’ on the Mountain Lion partition. Unlike 10.7 Lion, users delete PlatformSupport.plist. In ML 10.8 add that unique ID that you copied just now to PlatformSupport.plist. If you try to delete that Plist file, a Kernal panic will greet you during boot.

For MacBook 07 and 08 add this line right above MacBook6,1

For 08: MacBook3,1

For 07: MacPro2,1

8. Now, boot it back using the MacBook White and confirm that the ML is booting. If you did everything right, you should be able to reach the desktop, but have no accelerated graphics whatsoever, only framebuffer. (for MacPro1,1 and 2,1 with upgraded graphics card, you should get a perfectly working ML)

b) Use kexthelper (skip 10 – 13)

MacPro1,1/2,1 – upgrade graphics card to GT210 or HD 5770 No kext required. 7300GT untested!

MacMini2,1;3,1 iMac4,1;5,1 untested. Please try using above method depending on which graphics card you have and report back results! Thanks!

For ATI graphics card, i do not have a Mac to test them, I believe its the same, try ATIRadeonX1000.kext, ATIRadeonX1000GL.bundle, ATIRadeonX1000VA.bundle, ATI- yliadxos.bundle and report back.

10. Back to the MB white, install the kext using KextHelper and reboot.

11. After it reboots, you should be able to see a pop up message saying that the kext isnt compatible. If yes, reboot.

12. Boot into Single User Mode (Command+S ) and type the following:

chmod -R 755/Volumes/~MLPartitionName/System/Library/Extensions/AppleIntelGMA950.kext

chown -R root:wheel /Volumes/~MLPartitionName/System/Library/Extensions/AppleIntelGMA950.kext

Then remove cache and rebuilt:

rm -rf /Volumes/~MLPartitionName/System/Library/Extensions.mkext

kextcache -k /Volumes/~MLPartitionName/System/Library/Extensions

13. Reboot

14. Working Mountain Lion on not supported system.


The whole process is pretty similar to getting a Hackintosh running on unsupported Mac hardware, and assuming Apple doesn’t change anything it could be theoretically possible for custom third party OS X 10.8 installers to be created down the road specifically for the unsupported Macs. Maybe even with an easy USB installer? Who knows, but it’s also possible that Apple will bring support to these Macs in the final OS X Mountain Lion build, and it’s equally as possible that the next Developer Preview build will remove the ability for the above method to work at all. Ultimately we just won’t know until OS X 10.8 is finalized from Apple.

We don’t have a Mac to test this with, so if you run into any problems the best place to troubleshoot is probably the origin Forums thread on the matter at chúng tôi

If you try this, let us know! yliadxos

Update: Have a Mac Pro instead? Here’s a guide on how to install it on Mac Pro 1,1 and Mac Pro 2,1

How To Install And Run Stable Diffusion On Apple Silicon M1/M2 Macs

Stable Diffusion is a text-to-image AI that can be run on personal computers like Mac M1 or M2. In this article, you will find a step-by-step guide for installing and running Stable Diffusion on Mac.

You will need a Mac with Apple Silicon (M1 or M2) for reasonable speed. Ideally, your machine will have 16 GB of memory or more. You will need to wait longer for an image compared to using a similarly priced Windows PC with a discrete graphics card.

Here are the install options I will go through in this article.

Draw Things – Easiest to install with a good set of features.

Diffusers – Easiest to install but with not many features.

DiffusionBee – Easy to install but with a smaller set of functions.

AUTOMATIC1111 – Best features but a bit harder to install.

Alternatively, you can run Stable Diffusion in Google Colab which uses AUTOMATIC1111 (This is what I use and I am a Mac user). Check the Quick Start Guide for details.

Read this install guide if you want to install Stable Diffusion on a Windows PC.

Draw Things App

Install Instructions

Draw Things

Draw Things is an Apple App that can be installed on iPhones, iPad, and Macs. Installing it is no different from installing any other App.

App Product Page

It supports a pretty extensive list of models out of the box and a reasonable set of customizations you can make. It also supports inpainting.

Pros and Cons of Draw Things App

Common issues when installing AUTOMATIC1111 on Mac

I got “RuntimeError: Cannot add middleware after an application has started”

If you get the following error:

File “/Users/XXXXX/stable-diffusion-webui/venv/lib/python3.10/site-packages/starlette/”, line 139, in add_middleware raise RuntimeError(“Cannot add middleware after an application has started”) RuntimeError: Cannot add middleware after an application has started

This is caused by an outdated fastapi package. Run the following command in the webui folder.

./venv/bin/python -m pip install --upgrade fastapi==0.90.1

I got RuntimeError: “LayerNormKernelImpl” not implemented for ‘Half’

Start the webUI with the following command.

./ --precision full --no-half

Start webUI with the following command to remove this error.

./ --no-half

However, as of July 2023, the v2.1 768 model does not produce sensible images.

Web options to run AUTOMATIC1111

Consider the following options for running Stable Diffusion without installing it locally.

(I earn a small commission if you subscribe.)

Graviti Diffus

Graviti Diffus lets you use AUTOMATIC1111 without having a GPU. The service is provided remotely.

Apple Unveils Os X 10.10 Yosemite

Apple during the keynote here at San Francisco’s Moscone West just announced the next major version of its desktop operating system powering Macs. As rumored, Mac OS X 10.10 is codenamed “Yosemite” and focuses on clarity, translucency and precise typography resembling iOS 7. It also has a dark mode and much more, detailed right after the break…

Apple CEO Tim Cook opened his segment by noting that while the computer industry as a whole has declined five percent year-over-year, Macs grew by twenty percent.

The installed base of Macs has swelled to 80 million as a result.

Over 40 million copies of Mavericks have been installed sine its debut last Fall. That makes over 51 percent of installed base working on Mavericks versus just fourteen percent of Windows adoption.

It’s the fastest adoption ever of any operating system in PC history he said, jokingly remarking that “I knew somebody was gonna ask so I did a chart.”

There’s an all new Notification Center akin to that in iOS 7, except it can now show widgets from apps that export them.

There’s a brand new dark mode UI as well.

And, the all-new Spotlight appears anywhere on the screen under the mouse cursor and it now taps into the information both local and online, using a number of web sources, making it that much more useful.

For example, it’ll do movie showtimes, entries from Wikipedia, online maps, Bing results, restaurants and so forth

Spotlight will now collate information from a bunch of sources like before, presenting different pieces of data in a more obvious manner.

For example, searching for a contact would also produce a list of recent documents and email messages sent to Phil. Again, like before, only presented in a more visually pleasing manner.

You’ll also notice the translucent title bar of each window showing your underlying content.

Mail in Yosemite promises to be more powerful while addressing the fundamental problem with email – large attachments.

Now, with a technology called Mail Drop instead of your message bouncing off mail servers, you can send your attahcment up to five gigabytes in size encrypted via iCloud.

If your recipient has a Mac, they get the message just like before. If they are someone else, they get a secure link to an attachment where they can download the file. More on that feature in another article here.

The new Markup feature in OS X Yosemite Mail allows you to touch up image attachments without using a third-party application. For example, you could draw pretty arrows, add text, created cartoon bubbles and much more.

Sfari in Yosemite shows all your smart search suggestions and Spotlight suggestions right there in the completion menu, with previews of suggestion snippets, which is really nice. It can now Subscribe to RSS feeds that show in Shared Links and it’s better with a reworked tab view, with stacks for invidivual websites.

You can create a new Private window alongside your ordinary windows. Previously, launching a Private window would close all your existing windows.

It now supports SPDY, WebGL, HTML5 Premium Video to efficiently stream video and other modern technologies.

It’s more power efficient, too – up to two hours longer battery life for streaming from Netflix on a MacBook.

Another new Yosemite feature – Continuity.

This allows for much easier and seamless transitions between mobile and desktop devices. This extends to the new Instant Hotspot feature, Messages, phone calls and more.

For instance, when you receive a phone call, you Mac shows a notification. You can accept a call on your Mac and it can even use the computer as a speakerphone. More on Continuity is available in this post.

OS X Yosemite will be available this Fall as a free download this Fall.

Registered Apple developers can download a preview version of the software today and people who are on the OS X Beta Seed Program will be able to download Yosemite betas during the summer (so, not immediately).

Cog: A Great Itunes Alternative For Mac Os X

After iTunes erroneously deleted my music collection a few years ago, I started looking for alternatives. Being a part-time Windows user, I had grown to love the simplicity of Winamp, with its file and folder based music management. Unfortunately there was no port available on OSX. Thankfully, I stumbled across a little open source project named Cog.

Cog is a lightweight music player,  which supports many audio file-types including MP3, Ogg Vorbis, FLAC, AAC, Apple Lossless, Musepack, Monkeys Audio, Shorten, Wavpack, Wave/AIFF and much more. It also offers HTTP streaming, as well as some neat features like gapless playback, support for Apple remotes, chúng tôi integration and Growl notifications. Additionally, it lets you specify which audio output device to use, should you happen to have more than one.


The layout is as straightforward as they come. It has a window which serves as the playlist, into which you can drag and drop music from Finder or the “file drawer”. You are able to save and load playlists, and both m3u and pls formats are supported. There are also options to turn on shuffle and repeat as one would expect from any music player, and you are able to search the playlist to jump quickly to a specific file.

Music Library

Some people find iTunes’ management of our music folders less than ideal, in the way that it reorganises and renames files and folders. As mentioned earlier, my music collection suffered a catastrophic setback a few years ago when iTunes decided to delete the entire collection of files. I was able to recover most of it, but needless to say I’ll never trust iTunes again. Thankfully, Cog takes a very hands-off approach to managing your music.

Cog has what it calls the “file drawer”, which is basically an integrated finder window attached to the main playlist window. The first thing you’ll need to do is specify which folder to use as the base for the file drawer in the application preferences, as per the image below.

Shortcut Keys

Cog supports the Apple remote and also lets you specify shortcut keys in the preferences, under the “Hot Keys” tab.  It also offers full support for media keys, should your Mac keyboard have them. One issue you might run into, however, is that iTunes might also start when you use one of these keys.


All in all, if you’re looking for a music player that won’t chew up a lot of RAM and is fast and functional, Cog’s the app you’ve been waiting for.

You can find and download the latest release of Cog here.

Useful Terminal Commands & Tips For Mac Os X


Some tips may only work for a particular OS, though I’ve taken care to only select Terminal commands which should mostly work on Leopard, Snow Leopard and Lion.

Show Hidden Files

Though OS X doesn’t really place much emphasis on hidden files and folders, some files and folders are hidden by default. This is usually for good reason and deleting the wrong thing can cause issues, but if you wish to show the hidden files, then enter the following code:


write AppleShowAllFiles


To undo this command, replace true with false.

Enable 2D Dock

If you’ve ever moved your Dock to the left or right of screen (depending on which OS X version you’re running), you may have seen the 2D Dock shown above. If you’d like to enable the 2D Dock in all positions, enter the following into Terminal:



chúng tôi no-glass



Now restart your Dock to make the changes take effect by entering



To put your Dock back to normal, replace the “YES”‘ in the above code to “NO” and restart the Dock once again by entering the above killall command.

Disable Dashboard

I’ve never been a big fan of the Dashboard as it’s something of a RAM hog and I like it to be completely disabled in case I accidentally launch it. If you would like to do so too, enter this into Terminal and hit return:


write mcx-disabled



Once again restart Dock to make the changes take effect.



To undo this command and bring back Dashboard, just change “YES” to “NO” and restart your Dock by entering the killall command once again (note: the killall command can actually be inserted into the same line of code to save time, I’m making it separate here to give you a sense of what exactly is happening).

Show The Library Folder In OS X Lion

OS X Lion comes with the Library folder hidden by default but this can make troubleshooting any issues with your Mac, deleting the cache or just plain “tinkering” very difficult. In order to bring back the Library folder permanently, enter this command into Terminal:

chflags nohidden ~




Hide Desktop Icons

A nice clean Desktop looks great but sometimes it’s not practical to keep all your files organised. If you’d like to hide all the icons on your Desktop through a Terminal command, enter the following:


write CreateDesktop



Then our friend the killall command once again



When you wish to bring your Desktop clutter back, copy and paste the following:


write CreateDesktop



Then enter the killall command.

Launch An Application

In order to launch applications from the Terminal, just follow this template, replacing Twitter with the name of whichever program you’d like to launch:



Twitter Kill A Process

If you need to quickly kill a process or application, type the following into Terminal, replacing Twitter with whichever process you’d like to kill.


Twitter Open A Finder Window In Current Directory

To quickly open a Finder window in whichever directory you’re currently in, enter the following into Terminal

open . Change Grab’s Default Image Format

OS X’s built-in screenshot utility Grab is very useful but if you’d like it to save files as JPG, enter the following into Terminal:





(note: You can also change jpg to png if preferred).

Cut And Paste Files & Folders In Mac Os X

The Mac now has the highly desirable “Cut and Paste” file feature throughout the Mac OS X desktop and Finder, allowing users to truly cut and paste to move the selected documents or folders to a new location, rather than just making a copy of them. In this sense, the cut & paste ability behaves much like the Windows explorer counterpart, and it represents a fast and efficient way to move and relocate files from one location to another location, without using the standard drag & drop approach that has been standard on the Mac since the origins of the OS.

Using the cut and paste file feature can be seem a little tricky at first, but it’s really not complicated. All you need to do is learn to differentiate the keystrokes that make the action happen. Let’s cover exactly how to cut and paste to move files and folders around on the Mac.

How to Cut & Paste Files and Folders in Mac OS X with Keyboard Shortcuts

What you need to do first is select files in the Mac file system browser, known as Finder, and then combine a series of keyboard shortcuts. The keystrokes necessary for cutting and pasting files on the Mac are as so:

FIRST: Command+C copies the files or documents in the Finder, note they won’t be ‘cut’ yet

SECOND: Command+Option+V pastes the documents into the new desired location on the Mac, cutting it from the prior locating and moving it to the new location

Remember, you must have a file selected for the cut & paste to work on Mac.

Important: If you just hit Command+V you will only move a copy of the files into the new location, as in a true copy and paste, rather than a cut and paste function. Notice holding down the Option key also changes the menu text to show “Move Items Here” to further signify the difference if you use the menu based approach described below.

Cutting & Pasting Files on Mac with Menu Options

You can also cut & paste files and folders entirely from the Edit menu in the Mac Finder.

Select the files / folders you wish to move in the Finder, then pull down the “Edit” menu and choose “Copy”

Now navigate to the new location in the Finder where you want to ‘paste’ the files to

Go back to the ‘Edit’ menu in Finder and hold down the OPTION key to reveal “Move Items Here” (the Paste command changes to this, choose that to complete the file cut and paste in Mac OS X

You must hold down the “Option” key to reveal the “Move Items Here” choice to actually cut and paste (move) the files.

You’ll notice that you can’t select “Cut”, which is why you choose “Copy” in the Finder instead. The Copy command turns into “Cut” when you go to “Move” with the Paste command. You can watch this sequence directly by pulling down the menu itself to see the accompanying keystrokes as well, you’ll find it in all modern versions of MacOS and Mac OS X:

Being able to cut and paste files and folders is a feature many Windows converts have been wanting for a long time. Prior to this, users would drag and drop items into their new locations to move them, or use the command line mv tool. Those methods still work too as well, obviously, but the cut and paste methodology is a very welcome addition for many Mac users.

This works the same within MacOS Mojave, Sierra, macOS High Sierra, El Capitan, OS X Yosemite, OS X Mountain Lion and Mac OS X Mavericks, and will likely continue as a feature in the future versions of the MacOS desktop as well.
